Planting cultured disease tolerant oysters onto constructed three dimensional oyster reefs is a key element of the current oyster restoration strategy. Addition, or transplanting, of disease tolerant oysters essentially jump starts the restoration process by providing a population of oysters that are reproductively mature and capable of spawning during their first year in the habitat. The actual number of oysters available to spawn during the first year, as well as consecutive years, depends upon the abundance of living oysters. Beginning at the moment the oysters are planted and continuing throughout their lives in the river, the oysters are exposed to numerous sources of mortality including predation, disease, and burial by sediments. While we know that mortality reduces oyster abundance over time, we do not know how many oysters survive the planting process or the first few weeks after deployment. The objective of this monitoring element is to quantitatively document transplanted oyster abundance at restoration sites 2-4 weeks after the oysters are planted. Estimates of mortality immediately post planting are needed to evaluate planting technqiues as well as the initial number of oysters planted at a particular site to achieve a desired density of disease tolerant spawning oysters at the site.
